title: [A few reflections and definitions on the subject of embryonic research].
abstract: Tissue regeneration by embryonic stem cells (ESC) opens new applications for cellular therapy. ECS are used in endocrinology, rheumatology, cardiology, orthopaedics, dermatology and neurology. They come from supernumerary embryos given by their progenitors to science. The moral embryo status is the conflicting point and a hotly debated question. No ethical committee has given any valuable definition. Some countries have set time limits governing research with embryos, while others consider ECS as more akin to things or living beings such as animals.
